Colorado Rockies C Wilin Rosario could be traded following the team's recent signing of Nick Hundley. General manager Jeff Bridich said he had received interest in Rosario from clubs who were looking for a right-handed bat at last month's winter meetings. If Rosario is traded, Hundley would likely platoon with Mike McKenry behind the plate.

Baltimore Orioles C Matt Wieters (elbow) is scheduled to have Tommy John surgery on the ulnar collateral ligament in his right elbow Tuesday, June 17. His recovery time is expected to be nine months.

Fantasy Tip: You can safely drop Wieters in all redraft leagues. The good news is that he should be able to be ready to go for opening day in 2015. The Orioles, unless they make a play for a trade, are expected to continue on with a combination of Caleb Joseph, Steve Clevenger and Nick Hundley.
